4. A hinge comprising an inner member formed to provide arpartially' cylindrical pivot portion', complementary arcuate inner andn outer bearing portions spaced from said pivot portion and concentric therewith and an intermediate substantially straight connecting portion disposed substantially radially with respect to the bearing portion; and a complementary outer member having a partially cylindrical socket for reception oi said pivot portion, substantially straight portions diverging from said socket, the terminating edge of'one of said straight 'portions being slidably engageable with saidl innerl bearing portion,-and another portion extending from the other of said straight portions for slidably engaging said outer bearing portion.

6. In combination, a sheet metal frame member comprising spaced side walls and an intermediate portion at one edge of the Walls and integrally joining them, opposite side parts of the integral joining portion being merged together and extending in bent and contacting relation to provide a hinge part, the free edge of the contacting parts being dened by a reversed bending of the metal from one part to the other to provide a curved edge face.

7. In combination, a sheet metal frame member; comprising spaced side walls and an intermediate portion at one edge of the walls and integrally joining them, opposite side parts of the integral joining portion being merged together and extending in bent and contacting relation, the free edge of the contacting parts beingV defined by a reversed bending of the metal from onepart tothe other to provideA a curved edge face, the opposite edges of the sidewalls being inwardly and reveisely bent and directed between the walls 4and then extending toward each other to provide a channel havingv a. base between such walls.

8. In combination, a sheet metal frameand hinge part comprising any integral sheet. metal plate folded intermediate its edgesinto contacting and curved laminze defining a free edge having a curved edge face effected by.` the reverse ,bending of oney lamina tothe other, said con-A tacting lamina diverging at a point substan. tiallyr spaced from the free edge into spaced side Walls, and thelatter at their free edges being reversely bent and directed between the walls and then being bent toward eachother into substantiallyv edge contacting relation, to provide achannel having a base between thev Walls.

9. Incombination, a sheet metal frame member comprising spaced andx substantially parallelV side walls having portions at one edgeA reversely bent between the walls and? extending transverselyv with respect to the Walls -to providea channel having a base for receiving a glass or the like, the portions of the side Walls at the other edge thereof being merged together and extending in bent and substantially contactingf relation to provide a hinge part, and a sheet metal portion closing thefreeedge of the merged portions.
